DRAFT-BIGQING FOB RAILWAY-CASES.

Specification of Letters Patent. A Patented Apr. 15, 1919.

Application led July 26, 1916. Serial No. 111,364.

concise, and exact description, referenceA being had to the accompanying drawings, forming a part of thisspeciicatlon.

My invention relates to improvements in draft rigging for railway cars.

One of the objects of my invention is to provide a strong and elicient draft rigging.

A further object is to provide a-compound key tandem gear dispensing with the usual side plates, to provide stops for the gear. Further objects will appear from the description of the device herein following.

In the drawings forming a part of this speciication, Figure 1 is a side elevation, partly in vertical, longitudinal section ofa draft rigging embodying my invention. Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1. Fig. 3 is a cross section taken on line 3-3 of Fig. 1. And Fig. 4 is a rear end view of the s ring cage which forms a part of the draft rlgging shown.

Referring to the drawings, the numerals 5-5 indica-te draft members or parts of the car under-frame to which the draft rigging is applied. 6 indicates a tie plate secured to the draft sills by suitable means as for instance, the bolts 7-7. This is designed to support the draft rigging in its position between the sills. `A draw bar is shown at 8 having the usual butt 9 and being provided with the transverse slot 10 therein. A spring cage 11 is mounted immediatel back of the draw bar, the same being provided at its forward end with. a recess 12 to receive the butt 9 of the draw bar. The rear face of the re` cess 12 is formed by the plate 13 which is preferably integral with the upper and lower walls 14 and 15, respectively, of the spring cage. The cage is opxen at both sides and the bottom member 15 t ereof, which is adapted to rest upon the tie plate 6, is provided with lateral extensions 16-16 which are adapted to support the inner and outer yokes 17 and 18, respectively, which are hereinafter more compression resisting units comprises an outerspring 2.2 and an inner spring 23 nested therein. The front compression resisting unit is mounted within the spring cage 11., being seated at its forward end against the plate 13 and at its rear end against the rear transverse portion 24 of the inner yoke 17. The rear compression resisting member 21 is seated'at its forward end against the follower 19 and at its rear end against the transverse member 25 of the outer yoke 18. The follower 19 andthe rear member 25 of the outer yoke 18 are each preferably provided with a boss 26 to hold the rear compression resisting member in its position within the outer` yoke. The rear follower 19 is provided. at its top and .bottom with forwardly projected flanges 27-27 which surround the oli'- set portions 28--28 at the rear end of the spring cage, the said follower, through its engagement with the sprin cage, virtually forming the rear end thereo The two yokes 17 and 18 are mounted in horizontal position between thedraft members. The cuter yoke 18 is a Usshaped strap slotted at itsk forward ends as indicated at 29-29, for the passage of the coupler key 30, likewise the limbs of the inner yoke 17 which lie within the limbs of the outer yoke 18 are slotted near their forward ends as at 31-31, for the passage of the coupler key 30.

The coupler key 30 consistsof a straight key 32 that extends through the transverse slot 10 in the draw bar 8 and through the slots in the two yokes and passes at its ends through the slots 33 within the draft members, within which said key is stationary in the action of the draft rigging. The coupler key 30 also includes a U-shaped key 34, the free ends of which are turned rearwardly, the same partially inclosing the straight key 32 and extending with the straight key 32 through the draw bar and through the limbs of the yoke by being free t0 move longitudinallyl in respect to the draft member, such freedom being accomplished in the illustration of my invention appearing in the drawings by terminating the U-shaped key` within the inner faces of the draft members.

0n rearward movement of the draw bar, the same slides upon the coupler key 30, forcing the spring cage rearwardly and conillO pressing the front compression resisting unit -between the front member 13 of the spring I cage and the transverse lmember .24 of the inner yoke, which is held against rearward' movement by the coupler key 30. The rearwardlv moving spring cage. through its follower portion 19 compresses the rear compression resisting member-21 between it and the rear connecting member 25 of the outer '10 Vyoke 18; the Said outer yoke is held against -rearward movement by the coupler key 30. On forward .movement of the draw bar,

the U-shaped portion" 34 yof the compound key is drawn forwardly by the draw' bar, the f 15 engagement between the draw bar and the- U-shaped portion of the key being effected 42li of the spring cage, the spring cage being held against yforward movement through its engagement at its forward end against the member 32 of the compound key, as indicated at the numerals 36-36 in Fig. 2 of the drawings. Simultaneously, with the forward movement of the inner yoke, the outer yoke is drawn forwardly by the U-shaped portion .34 of the compound couplerv key compressing the rear compression resisting 85 unit 21 between the rear follower member 19 of the spring cage and the forwardly moving rear connecting member 25 of the outer yoke 1'8.

It will thus. be observed that my invention provides a draft gear in which a multiple of independent simultaneously operable compression resisting units' may 4be employed in tandem or other similar arrangement. It will be further observed that side casting to 45 provide stops for the draft gear may bel disposed with and that the connection between the draft gear and the car maybe effected through the use of a 4single compound key. 60 claim: r l.
